The larb-id may be remapped in the smi-common, this means the
larb-id reported in the mtk_iommu_isr isn't the real larb-id,
Take mt8183 as a example:
M4U
|
---------------------------------------------
| SMI common |
-0-----7-----5-----6-----1-----2------3-----4- <- Id remapped
| | | | | | | |
larb0 larb1 IPU0 IPU1 larb4 larb5 larb6 CCU
disp vdec img cam venc img cam
As above, larb0 connects with the id 0 in smi-common.
larb1 connects with the id 7 in smi-common.
...
If the larb-id reported in the isr is 7, actually it's larb1(vdec).
In order to output the right larb-id in the isr, we add a larb-id
remapping relationship in this patch.
If there is no this larb-id remapping in some SoCs, use the linear
mapping array instead.
This also is a preparing patch for mt8183.
